There are a couple of things I really like about Better GCal. The text wrap is brilliant, it's invaluable,and is the main reason I'm keeping this add-on. What a difference to be to read your whole month at a glance! I also like the option to collapse the header and sidebar, which tidies up the screen. It's a subtle difference but it matters.
What I don't like so much is that choosing the option to collapse the header and sidebar will switch your calendar view away from your Custom View, if you have one, to a built-in view. There's no way to select your Custom View after the header is collapsed. Also, I miss the Today button when I'm viewing another month. If those issues could be fixed, I'd give this addon 5 stars. Thanks for your work, it's appreciated.
